All of the devices feature significantly different styling, and have their own advantages and disadvantages, but the Nokia Lumia 1520 was found to have the superior build quality, best screen and of course best camera.

The other two devices did however have interesting features such as IR Blasters and the superior speakers on the HTC One Max.

The multi-window capability on the Samsung Galaxy Mega reminds me quite a bit of multi-tasking on Windows 8/RT, and I can image a future fused version of Windows Phone and Windows RT will make better use of the increasingly large screens on our phones.

The reviewer concludes:

Based on the camera, I have to say something crazy: the Lumia 1520 might actually be the best of this bunch of devices. I’ve made it no secret that I think Android is a better operating system than Windows Phone, and 9 times out of 10, I’d choose HTC or Samsung over Nokia. But among this set of huge phones, you can make an argument for the Lumia 1520 because of its superior camera, great screen, and Windows Phone not being as far behind today on apps. The Galaxy Mega is a distant third in the race, so if you’d like to get a large screen Samsung, sacrifice a few millimeters and get a Galaxy Note 3. In terms of this lot, it comes down to choosing between a One and a Lumia 1520. If you take a lot of pictures, get the Lumia 1520. If you tend to download a lot of apps and want them soon, grab the One Max.
